4 Claims. l

My invention relates to chairs, and particularly to a sportsmans chair which is adapted to be used by fishermen, campers, and the like, the chair being so constructed that it may be folded into a compact unit for transportation, and unfolded and placed on a boat or any other boardlike surface or support. It is the principal purpose of my invention to provide a chair of this character, which is simple and sturdy in construction, and which involves a minimum number of parts to provide a swiveled comfortable chair.

My invention contemplates a chair construction comprising a clamping base which can be secured, for example, tothe seat boards in a row boat, and which provides a swivel for the seat and back portion of the chair, such seat and back portion being so constructed that they may be folded together. The back portion is held in suitable adjusted position with respect to the seat by side members which form arm rests when they are raised into back rest supporting position.

The nature and advantages of my invention will appear more fully from the following description and the accompanying drawings wherein a preferred form of the invention is shown. It should be understood, however, that the drawings and description are illustrative only, and are not to be taken as limiting the invention except insofar as it is limited by the claims.

In the drawings:

Figure 1 is a view in side elevation of the seat and back rest portion of the chair;

Figure 2 is a plan view of the chair;

Figure 3 is a front elevational view;

Figure 4 is a bottom plan view of the chair;

Figure 5 is a plan View showing the clamping base as attached to a supporting board, and

Figure 6 is a sectional view on the line 6-6 of Figure 5.

Referring now to the drawings, my invention is embodied in a chair which is particularly adapted for use by sportsmen in boats and around camps, the chair being of such a nature that it can readily be packed and thus transported in the back of a car. The construction is sturdy and strong, and the parts are so made that if damage occurs to any single part, it can be readily replaced without the loss of the other parts of the chair.

As shown in Figures 1 to 4, inclusive, the seat and back rest portions of the chair comprises a seat frame member l0 consisting of a piece of tubing bent to substantially U-shape, and flattened at its ends. The legs H and I2 of the U-shaped member are connected by tubular braces l3 and I4, which converge from their ends where they are welded to the legs H and I2 toward the mid portion where they are welded to a stem l5 that has a socket l6 therein, and a disc I? at the lower end thereof. The seat portion consists of a relatively thin board it of any suitable material such as a composition board, or plywood. The seat board may desirably be fastened by screws to the member It. At the ends of the legs H and J2 upstanding back rest mounting bars I9 and 29 are welded, and these bars serve as a means to secure the lower ends 2| and 22 of two uprights 23 and 2 3, which are connected by a spring cross bar 25 at their upper ends. The cross bar 25 is bowed as shown for purposes of comfort. A flex ible back rest 25 is provided with tubular end portions 2! and 28 which are cut out as indicated at 29 and 30. The back rest 26 may desirably be constructed of a fabric such as canvas.

In order to maintain the back rest comprising,

the members 23, 24 and 25, at the desired position, I provide two tubular side frame members 3| and 32 These side frame members are bent to the shape illustrated in Figure 1, and have their lower ends flattened as indicated at 33 and 34. These flattened ends are fastened to upstanding bars 35 and 33 which are welded on to the legs I l and I2 toward the front of the seat portion of the chair. Bolts are used for securing the frame members 3| and 32 so that they may be folded over from the full line position shown in Figure 1, to the dotted line position illustrated in this figure. The frame members 3| and 32 have their rear ends slotted as illustrated at 37 and 38, and they have short bars 39 and 40 secured in the ends thereof by means of suitable bolts. The slots 3'! and 38 are in the downwardly facing edges only of the tubular frame members 3| and 32, and the pivot points of the bars 39 and 40 are so positioned that the bars when extended as shown in Figure 1 will strike the upper inner surface of the tubular frame members 3| and 32, and cannot be folded upwardly any further. The bars 39 and 40, however, can fold to substantially right angles with respect to the members 3| and 32 as illustrated in the dotted lines in Figure 2 of the drawings. The tubular uprights 23 and 24 have apertures therein shown at 4| and 42, through which the bars 39 and 40 may extend. The bars have adjusting holes 43 therein and pins 44 are used to secure the back rest comprising the members 23, 24 and 25 at the desired angle with respect to the seat. The members 3| and 32 are preferably provided with flat arm rest portions 45 and 46 as shown in Figures 1, 2 and 3 of the drawings.

In order to support the seat part of the chair 50, 5! and 52 in position. Each of the'bars 49,

50, 5| and 52 carries at its outer end a down.- wardly and inwardly" directed flat Iiielhbi 81'' which has a clamping screw 62 threaded through it. Figure 6 of the drawings illustrates how the screw 62 is used to clamp the assembly to a support such as the board 63. The tubular bars 41 and 48 are secured in spaced parallelrelation by two cross ties 64 and 65 which are alsdt'iibiilar' and which are welded to the-Bars 4! and 48; Cross bars 64 and 55 form a support for a disc 65 which is welded thereto and this disc hasan up standing stem 51 adapted to seat in the socket I5 for pivotally' supportingthe seat part'of the chair;-

It will be observed fro'm Figure 1 and Figure 2 that the entire-seat 'portio'h of'the chair'and the back-rest andside ar I'nscan be folded down into a-compact'ajssembly. The supporting base consisting of the bars'41 and 48 and theparts attached thereto ma'y be'sepa'rated from the seat portion and packed independently thereof; yet the entire assembly when put together provides a comfortable-swivel chair foruse'inboats and the like; The canvas backlii is, of course, easily removed-and'replaced; In fact ifthe back rest itself is damaged or destroyed the chair can beeasily put in' operative condition by's'ubstituting anew 'back rest and this-is true of all parts of the chair. The' partsare'separabla' and any par-' ticular part neededrnaybe replac'ed without-the necessity of purchasing'a complete-new chair;

Having thusdescribedmiy invention,--I claim: 1. A sportsman s chair 'comprising a combination a; clamping base having spaced apart ex tensib'le bars" provided with Hook ends for se-' cu'rement to a; boat seat; crdss ba'r means c'onnecting said extensibie' bars-aind a swivel p'iiron saidcross bar means; a seat franie coinprisirigan U shapedframe, cross bar means -connecting the 7 legsof said'seat frame and a'socket-fixd on said last named-cross-bar meansto ireceive said pin? 2.
